My invention relates to window screens, and has particular reference to an improved screen comprising upper and lower sections, which sections cooperate to completely fill the window frameto efiectively prevent the ingress of flies or other insectsintothe room.

An object of my invention isto provide a two-piece window screen comprising an upper and lower section which normally cooperate to cover the entire window opening, and in whichthe several sections are so associated, and mounted that one section can be moved to lie parallel to the other section when is desired thatonly one half of the window open- 5. ing be covered or screened A further object of my invention is to pro-' vide a twopiece window screen comprising an upper and lower section-for normally cooperating to cover the entire window open ing and in which the lower section may be removed from the window and the upper sec-- tion lowered into the position normally occupied by the said lower sectionwhen'it is desired thatonly one'halfof the window opening be covered or screened. I

A further object or my invention is to provide a two-piece window screen comprising an upper and lower section which normally cooperate to .cover'the entire windowiopening,

and in which the upper section is so mounted that it can be moved inwardly and down wardly to lie parallel to the lower section thus to torm a double screen, covering only the lower half of the window opening, or, if desired, the lower section may be completely removed'from the window frame and the upper section moved downwardly into the position normally occupied said lower removable section. I Q

A still further object of my invention is to provide a simple, inexpensive" and .eflicie'nt meansfor permitting. the upper section of the screen to be moved'inwardly to clear the upper edge of the lower section'and down-l wardly to lie'parallel to the said lowersection, these'movements being. permitted through the instruinei'itality of a pair of double. leaf hin 'es, one end .of each of said hinges being pivotally connected to a side mem- 50 her of the frame of the upper screen section and the other end of each of said hinges being pivotally and slidably mounted. on vertical guide rods positioned adjacent each side edge of the window frame; p i v In the accompanying drawings, wherein,

Y Upper and lower-sash members 5 and 6' respectively 7 are mounted for vertical movement within the trame, itbeing understood that said sashes are properly balancedby sash weights, (not shown), and thatsaid sashes are guided and. confined in their vertical movements by guide strips or beads 7 on the bottom of the head member 2 and on the inner sides of the side members 3. All of the aboveiconstrud tion" is old and well known in tl1e ]art" and forms no 'part of my present: invention.

While I have elected to illustratemy invena "F tion as applied to theordinary, sliding sash window construction, it is ltobe understood,

that the invention is not limited to use with such construction and that the same may be used with any type of sliding, swinging, or 1w 1 combined sliding and'swingiiig window sash construction, the invention being particularly well adapted for use in connection with the combined sliding and tilting window sash construction shown in the copending applica tion of Harry A. Hendren and Oscal Kai-lslyst, Ser. No. 189,040, filed May 5, 1927.

The lower section ofmyimproved twopiece screen comprises rectangular frame member 8 covered with suitable screen material 9 held on the said frame by a retaining bead 10. The outer marginal edge of each of the side frame members of this lower section I is cut away to form a vertical channel 11 as best shownin Fig. 7, and this channel coop-I crates with'a head 12 nailed or otherwise secured to the inner side surfaces of each of the innermost guide strips orbeads 7 opposite sides of the window frame, said channel 11 and head 12 cooperating to guide the lower section and to maintain the same in parallel spaced relation with the lower window sash 6. Iiiiorder tomaintain the lower scrcen section in a position parallel to the lowerwindow sash 6 and to'permit its ready placement, to and removal from such position, I provide the frame 8 with spring progectod latches or catches 13 located on opposite sides the frame, these latches'or catches comprising a cylinder ll inserted within the edge of the frame and having a bullet-shaped member 15 adapted to be forced outwardly by a compresinnersurface ofthe top and bottom m mbers sion spring 16 and to be moved inwardly against the. action of said spring either by movement of ahandle 17 or by an inward pull on the screen frame 8 when it desired to removethe same from the ,window-ope;..' Suitable'handholds 18 are providedin the ofthe frame 8 and these handholds assist in inserting'or removing the frame 8, it being understood that when the said frame is placed in position to cover the lower half of the windowopening, the channels or grooves 11 engage the vertically extending beads or guide strips 12 to prevent further inward move ment, and the spring latches 13 serve to maintain the said frame in position witliin the window opening due to the frictional contact be tween the outer ends of the bullet-shaped bolt members '15 and the side walls of the side heads 7. The upper edge of the top memberof the frame 8 is slightly convened orcrowned for a purpose. to be hereinafter referred to.

The upper section of my improved twopiece screen comprises 'a rectangular frame member 19 covered with suitable screen mater1alj20 held on the said frame by the retaining str1p21. The outer marginal edge of each ofthe side frame members of the upper section 19 is cut away to form a vertical channel 22 as best shown in Fig. 5, and these channels cooperate with the'beads or guide strips 12 nailed or otherwise secured to the inner side surfaces of eachof the innermost guide strips or bead-s 7 at opposite sides of the window frame, said channels 22 and beads 12 cooperating to main tain this section in parallel spaced relation with the upper window sash 5 and to maintain saidiupperfsection '19 in vertical alineinent immediately above the lower section 8.

The lower edge of the bottom member 19 is slightly con'eaved or grooved to accommodate the upper convert or crowned edge of the top member of the lower section 8 when the two sections are placed'in verticalfalinement as 7 shown in the drawings. Suitable handholds' are provided in theinner surface of the top. w

and bottom members of the frame 19 to assist. in moving said frame nto the desired posi-l tion. I n I .1

Positioned at opposite sides of the window frame 1 adjacent each of the innermost side guide strips or beads .7, are vertically extend- .ing rods 24, eachextending the fullheight of the window frame and each fastened to the head board 2 and sill 1 by screws or other fastening means. A-double leaf hinge member 25 has its two leaves 26 and 27pivotally connected at their inner ends. The outer end. of each leaf seas rolled over the rod 24- to form a pivotal and sliding connection therewith, while the outerend of the leaf 27, is pivotally connected to a plate 28 screwed or otherwise fastened to the side member of the name-i9.

As will be apparent. from aninspection of Fig. 1 of the accompanying drawings, a rod 24: and adouble leaf hinge 25, is positioned and.

secured at each side of thewindow, the length of the leaves 26 and 27-.being such that the section 19 may bemoved inwardly'f-rom its normal position invertical,alinementfwith the lower section 8 to a position such as shown in dotted lines n Fig. 5, wliereupon,'saitl upper section may be moved downwardly along the rods 24: toa position immediately in rear of and parallel to the lower section 8.

Referring now, to the operation of the twopicce screen above described, it will be ap parent that when it is desired to utilize the construction to completely fill] the window frame,the lower section 8 is placedin the frame and moved outwardly toward the lower sash 6 until the channels or grooves 11 abut against the heads 12. Duringgthis out" the upper screen section is then placed in the e frame and moved outwardly toward'the upper sash 5 until the channels or grooves 22 abut-the beads 12, at whichtime the said section 19 is in vertical alineinent with the lower section 8 and hasits bottom edge resting on the upper edge of the lower sectin'8. The plate 28 is then screwed or otherwise fastened to the side frames of the upper section 19.

lVhen it is desired that onlythe lower half of the window opening be covered or screened or when it is desired to obtain access to the upper sash for the purpose'ot adjustment, repair or cleaning, the operators hand engages the handholds 23 and the upper screen section is lifted sufiiciently to disengage the convex or crowned upper edge of the lower section from the concaved or grooved bottom edge of the upper sash. The upper sashis then moved inwardly a suthcient distance to clear the lower screen section, at which time the upper section may be moved downwardly along the rods 2 to a position parallel to the lower screen section 8. When in this position, a double screen is formed by the sect-ions 8 and 9 which cover only the lowerhalt of the window opening. When it is desired that only the lower half of the window opening be covered or screened with a single thickness of screen, the operator lifts the upper section 19 upwardly a suliic-ient distance to disengage the convened or crowned top edge of the lowersection 8 from the concaved or grooved bottom edge of the upper section 19, and by pulling the lowersectioninwardly with the aid of the handholds 18, the latch members are forced inwardly against the spring 16 and the. frictional contact between such latches and the innermost beads 7, is easily overcome to permit the lower section 8 to be readily removed from the frame. If, for any reason, the inward pull of the lower section 8 is not sulhcient to slightly depress the spring-pressed. latch member 15, the opera tor, by movement of the operatinghandles 1'4", may cause said latch members to move inwardly a suthcient distance to overcome any resistance offered to theremoval of the lower section from the window frame. After this lower section 8 is removed from the window opening, the upper section 19is moved downwardly along the guide-rods 24 until its bottom edge contacts with the sill 1-, at which time the upper section 19 occupies a position previously occupied by the lower re movable section 8. p

It will thus be seen that I have provided a window screen comprising upper and lower screen sections which are normally arranged one above the other in vertical alinem'ent'to completely fill the window opening, the two sections, when in this position, being maintained in vertical alinementby means of the it guide strips or'beads 12 fastened to the wintion, means have been provided for permitting the upper. section to be raisedslightly,

moved inwardly a sufficient distance toclear the top of the lower section, and thento be moved and guided downwardly to occupy a position parallel to; the lower section, such movements being permitted by means of the double leaf hinge members 25 and their asso-' ciated guide rods 24. I have further pro vided a novelmeans for permitting the ready removal or"- the lower section from the window frame, to permit the upper section to be moved and guided downwardly to occupy the position or space previously occupied by said lower removable section.

It is'to be understood that this form of my invention herein shown and described is to be taken as preferred embodiment of the same and that various changes may be made in the size, shape and arrangement of parts, ithout departing from the spirit of my i11- vention or the scope or" the subjoined claims Ha 'ing thus described my invention, what Iclaim is: I

' 1. A windowscreen comprising an upper and lower section normally maintained in vertical alinement one above the other tocompl'etely fill the window opening, vertical guide rods mounted at opposite sides of the windowbpening, and hinge membersslidably mounted on the guide rods and pivotally connected to the upper section, whereby said section may be moved inwardly and then guided. downwardly to occupy a position parallel to the said lower section.

2. A window screen comprising an upper and lower section normally maintained in vertical alinement one above the other to completely fill. the window opening, vertical guide rods'mounted at opposite sides of the window opening, and hinge members pivotally connected to each side 01" the upper section and pivot-ally and slidab'ly. connected to eachoi the vertical guide rods, whereby said upper section may be moved inwardly a sufli cient distance to clear the lower section and then moved and guided downwardly to 00- cupy a position parallel to the said lower section.
